(author), TNO Defensie en Veiligheid TNO Industrie en Techniek (author)A robust and efficient method is presented for recognizing objects in unstructured 3D point clouds acquired from photos. The method first finds the locations of target objects using single spin image matching and then retrieves the orientation and quality of the match using the iterative closest point (ICP) algorithm. In contrast to classic use...conference paper 2010
